Check which process call a file

[huongbuixuan]

Hi all
How can I determine which process call a file ( it is share library)?. when I used fuser command, it is only list user used this file, not process.

Thank

you can use

fuser -u

check for the u option of fuser.

If this is not helpful,then you should use the lsof utility.

grab the lsof for 64 bit from here

ftp://vic.cc.purdue.edu/pub/tools/unix/lsof/

32 bit is here

Hi,

Unfortunately 'fuser' is not very good. As suggested, get hold of the 'lsof' tool. Below are some example on it's usage.

To which files are open for a given process id (pid)

# lsof -p

To see all the open files associated with a particular command.

# lsof -c midaemon

User name.

# lsof -u
# lsof -u

processes being used via a socket.

# lsof -i tcp:23
# lsof -i udp:123

fuser is a childs toy compared to

lsof

Here's some other links to where you can get 'lsof'.
